摘要： An object is to improve the durability of the stiffener having a hard rubber member and a soft rubber member formed on the radially inner side and the radially outer side by laminating rubber strips. A tire includes bead cores, stiffeners provided on the outer circumferences of the bead cores, and a carcass ply. Ends of the carcass ply are disposed on the stiffeners. Each stiffener includes an inner rubber portion on the radially inner side, an outer rubber portion on the radially outer side, and a cover tape. The inner rubber portion is formed by laminating a first rubber strip. The outer rubber portion is formed by laminating a second rubber strip. The second rubber strip is composed of rubber having a lower rigidity than the inner rubber portion. The cover tape covers a part of the stiffener that comes into contact with the end of the carcass ply.
